Growing kale in zone 7
Spring kale is good; fall kale is better — light frosts convert starches to sugars. Harvest outer leaves and the plant keeps producing for months. In zones 7+, kale often stands all winter.
Zone 7 covers upper South (Virginia, Tennessee, Oklahoma), New Mexico highlands — long season with mild winters — overwintering hardy greens becomes realistic. Zone dates are medians: frost timing varies within a zone with elevation and terrain, so treat these windows as a solid default and refine them with your own city’s dates below.

These windows use zone 7's typical frost dates (last frost ~Mar 30, first frost ~Nov 3). For windows computed from your frost dates, run the ZIP code frost lookup and open the planting calendar — it remembers your city. The seed starting scheduler turns the whole seed rack into one printable, date-sorted list.
Frequently asked questions
When do I plant kale in zone 7?
Transplant Mar 2 – Mar 16, counted from zone 7's typical last frost around Mar 30. As a hardy crop it tolerates the light frosts on either side of that window.
When should I start seeds indoors for kale in zone 7?
Sow indoors Feb 16 – Mar 2 — that's 6 to 4 weeks before the typical Mar 30 last frost, giving sturdy transplants exactly when the garden is ready for them.
Can I direct sow kale in zone 7?
Yes — direct sow Mar 2 – Mar 16. Transplants buy a head start, but direct-sown plants catch up quickly once soil warms.
Can I plant kale for a fall harvest in zone 7?
Yes — sow Aug 11 – Aug 25, counted back from the typical Nov 3 first frost so plants mature before serious cold. Light fall frosts improve flavor rather than ending the crop.
